Ignition Wire Service
Spark plug wires carry an enormous electrical charge from the ignition coil or distributor to each spark plug, and that constant high-voltage stress combined with engine heat eventually breaks down their insulation. Automotive Super Center inspects and replaces ignition wires as part of a complete tune-up, and scheduling the work online takes just a few minutes.
Since 2001, we've kept ignition systems firing reliably for East Texas drivers, including plenty of older vehicles still running this style of ignition wiring.
What Spark Plug Wires Do
Ignition wires route the high-voltage pulse generated by the ignition system to each spark plug, where that charge jumps the plug gap and ignites the compressed air-fuel mixture. Internally, they use a resistive core wrapped in heat-resistant insulation designed to contain that voltage and suppress electrical interference.
Not every modern vehicle uses spark plug wires at all. Many newer engines use coil-on-plug ignition, eliminating the wire entirely. Vehicles with a distributor or a remote coil pack still rely on wires, and those are the ones where this service applies.
Our Ignition Wire Services
Wire Resistance Testing
We test each wire with a multimeter to check for resistance beyond acceptable limits.
Full Set Replacement
We replace the complete set together rather than swapping a single wire, since they age at a similar rate.
Distributor Cap & Rotor Service
On vehicles that use a distributor, we inspect the cap and rotor for wear at the same time.
Why This Service Matters
- Degraded wires with high resistance weaken the spark enough to cause incomplete combustion and noticeable misfires.
- Cracked insulation can let voltage arc to a nearby metal surface, disrupting ignition timing.
- A persistent misfire from bad wires can send raw fuel into the exhaust and damage your catalytic converter.
- Strong, consistent spark across every cylinder is directly tied to both power delivery and fuel economy.
- Replacing wires as part of scheduled maintenance is far cheaper than dealing with resulting converter damage.
What to Expect at Automotive Super Center
Ignition wire service at Automotive Super Center is typically bundled into a complete tune-up. We test existing wires, replace the full set when warranted, and check the distributor cap and rotor on applicable vehicles. As an East Texas company committed to service excellence since 2001, financing and our Nationwide Warranty are part of every visit.
